Claims.

My invention relates to a novelty yarn and a novel process of making the same and more particularly my invention relates to a yarn comprising a multiplicity of decorative threads twisted over a core in such a fashion that each decorative thread forms a multiplicity of adjacent knops, the multiplicity of decorative threads forming a distinct set of knops with a repeat pattern along said yarn.

The most important" considerations in the manufacture of the novelty yarn are to obtain distinct novelty efiects and at the same time to get a reasonably light yarn so that it is not too costly and so that it can be used in a variety of fabrics.

In the novelty yarn of my present invention I obtain variegated effects in the form of a repeat pattern which is made up of a multiplicity of knops, as for example twoadjacent knops, formed from a single decorative thread and a multiplicity of decorative threads, such as for exv ample five, being used to form aseries of i0 knops for each repeat pattern, the ten knops being formed two each from the five. different decorative threads.

The method of making my novelty yarn is such that an extremely light decorative yarn is obtained especially with regard to the variegated decorative effect obtained by the use of a multiplicity of decorative threads.

It isthe object of my invention to provide a novelty yarn having. variegated efiects in a repeat pattern.

It is a further object of my invention to provide a novelty yarnmade up of a series of different and distinct decorative threads.

It is a further object of my invention. to provide a novelty yarn which has as its primarily decorative motif a series of a plurality of knops of a multiplicity of. decorative threads.

It is afurther object of my invention to provide a novel method of twisting about a. core a plurality of decorative threads so that: each decorative thread forms two adjacent knops, the decorative thread being then twisted about the yarn until the knop pattern is repeated.

These and further objects of my present invention will be apparent from a consideration of the drawing and the specific description thereof which here follows:

Figure 1 is a perspective of the novelty yarn of my invention.

Figure 2 is a side view of the apparatus employed in forming the novelty yarn of my invention.

Figure 3 is a front view of the apparatus which illustrates the method of forming the novelty yarn of my invention.

Figure 4 is a detail. showing the stage in the process of the manufacture of my novelty yarn next after-that shown in Figure 2.

Referring now' more specifically to the drawing, in Figure 1 I show a novelty yarn generally denoted as I0, which comprises two knops II and I2 formed. from a thread of decorative material 13 which may, for example, be rayon. Immediately adjacent the two knops H and [2 of decorative material l3, are knops l5 and it formed from a. second decorative material ll,

which knops may be, for example, of worsted.

Knops l9 and 20 formed from decorative material 2| are positioned adjacent knops l5 and I6. After knops l9 and 20 come knops 22 and 23 which are formed from still another thread of decorative material 24 which may be, for example, worsted. Seen at the extreme right of Figure 1 are knops 26 and 21 formed. from a thread of decorative material 28 which may be, for example, worsted.

The knops aforementioned are twisted over a suitable core which, as shown, is made up of two threads 42 and 43, of, for example, cotton or the like. The novelty yarn is bound back with the binder 3|.

The. various decorative threads employed preferably are distinct and difierent from one another and particularly the respective sets of adjacent knops, such .as knops l5 and I6 are distinct in. appearance and in contrast with knops l9 and. 20; It will be recognized, that the knops II and: 12 are similar to one another and are formed from the same thread of decorative material l3, and similarly knops l5 and it are formed from the same thread of decorative material ll.

The threads of decorative material employed may be rayon, worsted, wool, silk, mohair or any suitable decorative material, and the pattern in which five different decorative threads are employed as shown in Figure 1 is repeated along the yarn as will be more particularly pointed out hereinafter.

In Figure 2 I have shown an apparatus comprising suitably mounted reels 40 and 4| from which are drawn core threads 42 and 43. The .core threads 42' and 43 are drawn between idler roll 45 and the driven roll 46. Roll 46 has a sprocket 41 shown in dotted line mounted on one end thereof and this sprocket 41 is driven 2 a I by pins 48, 49 etc. mounted on the driven wheel 50.

By means of this driven pin and idler sprocket arrangement, an intermittent motion is effected in the roll 46. Core 42, 43 moves downwardly and about this core are twisted the decorative threads l3, l1, 2|, 24 and 28 which are drawn from suitable mounted rols 51, 58, 53, 60 and 6|. The decorative threads which, as above, may be threads of rayon, worsted, wool, silk, mohair or any suitable decorative the continuously moving set of rolls made up of idler roll 64 and driven roll 65. The threads l3,

l1, 2 I, 24 and 28 of decorative material pass over faller bars 10, H, 12, 13 and 14', respectively, and

material are drawn by y am.

form knops over the core 42, 43. The knopped yarn I which is formed then passes through the guide 16 and through the traveller l1 and thence is wrapped around the driven bobbin 18.

The method of my invention is as follows:

The core 42, 43 is moved downwardly in intermittentmotion by the pins 49 on the wheel 50 so that the core stops in front of the faller bars 1U--'l4 and after a predetermined period during which knops ll, l5, I9, 22 and 26 are formed on the core by the threads of decorative material l3, l1, 2|, 24 and 28, the core=again moves down a short space .at which time,.as shown more particularly in Figure 4, the knops l2, 5,20, 23 and 21 are formed adjacent .to the firstformed knops, so thata pattern of ten knops, each two of which are similar and formed from the same decorative thread, are formed over the core 42, 43. The two adjacent knops being ofthe same decorative material and therefore the same color and appearance form a novely yarnhaving a multicolor effect in which, for example, areas of blue, gold, red, green and white forming a repeat pattern, occur in regular sequence.

After the two knops such as II and I2 are formed from the thread of decorative material l3, and similarly the other knops are formed from other threads of decorative material, the pins 48, 48 etc. by reason of the rotation of the wheel 50 engage the sprocket 47 and turn the roll 46 for a suflicient length of time to move the knopped yarn down completely beyond the faller bars and to bring a new portion of the core -4243 into position by the faller bars 14 so that another set of knops can be formedon that portion of the yarn.

By means of the process above set forth, I employ a minimum of decorative thread material and the decorative thread may be light in weight because of thecombination of threads involved so that I obtain a distinctive novelty yarn which is extremely light in weight, reeling as for example in the case of the use of fourdecorative threads of worsted and one decorative thread of rayon, about 962 yards of novelty yarn. to'the pound. It will be realized that this is light weight novelty yarn and hence of definite value.

It is to be understood that it is within the purview of my invention to form a multiplicity of adjacent knops of the same decorative material. That is, in lieu of the two knops of the same dec- Certain variations in the method of manufacure will be apparent to those skilled in the art.

It is my intention, therefore, not to be limited by the particular examples of the yarn and method of making the same which I have set forth by way of specific example of my invention, but only by the claims hereto appended.
